“”If the righteous one is scarcely saved,
Where will the ungodly and the sinner appear?” ~ 1 Peter 4:18

Even Christians often get jaded and forget they are only saved because of Christ as my personal account shows above. Our righteousness is positional, not actual, eventually (hopefully) practical and even then only because of the position Jesus places His own.
So if Christians are so "scarcely saved, what danger is there for those who do not have a saving faith in Him?
Heaven will only be exciting because no one there will be able to brag about how they got there.
We will be too busy thanking Jesus.
So what is the answer for both the saved and unsaved?
Only the wisest are the most trustingly, repentantly dependent on Jesus Christ alone.
